To all whom t may concern:

Be it known that I, ,ANTHONY HEIMER- v MAN, a citizen of the United States, residing at Syracuse, in the county of nolidaga and State of New York, have invented a new' passing through the coupling members, and` in which such pressure holds the parts in locked position as long as such pressure continues, the members being released and readily detachable when the water is cut oil".

With this object. in f, view the invention consists in the novel features of const-ruction hereinafter described, pointed out in the claims and shown in the accompanying drawings in which y Figure 1 is a longitudinal section showing coupling members at opposite ends of the hose, intermediate portions of the hose being cut out, the coupling 'members being shown in interlocked position. .Fig 2 is an enlarged section on the line 2-2 of Fig. l. Fi 3 is a similar section on the line 3-3 of Pig. l.

In the drawings 1 and 2 represent respectively coupling members at opposite ends of the hose, the member l being adapted to be connected to a plug, engine or other source of water supply, and the m'ember 2 beingv reduced to form a discharge nozzle. In-

ter-mediate members 3 and 4 coperate respectively with the members 1 and 2. So tar as the locking mechanism is concerned the coupling member 1 corresponds with the member 4, and the member 2 with the member 3. A detail description therefore vof the coperating members 1 and 3 will give a clear idea of the construction of all the coupling members which might be-employed, as the number of these wouldof course depend upon the length of the pipe and the number of sections of vhose coupled,

together to complete the pipe.

5 indicates the usual hose secured to the members 3 and '4 in the usual manner.

Coupling member 1 is threaded as shown at 6 to adapt it to be connected `to a suitable source ot water supply and at the end opposite `the threaded portion is enlarged in diameter as shown at la. The member 1 is rovided with two inwardly extending blades 7, set oblique to the longitudinal axis of the coupling member, said blades being arranged opposite each other and being also arranged on intersect-ing lines. Similar blades 9 are carried by the section 3, but are arranged just the opposite of the blades 7, so that when the water under high pressure strikes the blades 7 and tends to turn or rotate the member 1 inv one direction it will also strike the blades 9v and tend to turn or rotate'the member 3 in the opposite direction.`. In orderV that this turning movement imparted to the members by the pressure of the water may cause them lto interlock I provide the member 1 with locking lugs' S'whichvare carried by the body por tion of the coupling and extend longitudinally into the enlarge portion, thereby b ing spaced from the sidesof the coupling member. These lugs, of which there are two, placed opposite each other, are provided at their free ends with inwardly turned T- heads Sa. The member 3 is also slightly enf1 larged at its. meeting end and is provided with an angled slideor guide way 10 formed by parallel angledv ribs 11 and 12, the inner end of the guidewaybeing closed by a cross rib 13. vThe rib 12 has a portion of its inner face slightly cut away to form a shoulder 14. The guideway thus described is duplicated onropposite sides of the member 3, one guideway being formed for each lug 8.

The member 4 is also provided with blades 7 and lugs 8 and the member 2 with blades 9 and guideways 10.

In use thecoupling members are presented to each other so that the heads of the lugs 8 willY enter the 4guideways 10, as soon as the water-pressure is turned on it will act on the two sets of blades 7 and 9 and the T-heads 82l will slide to the innerrends of the guideways and drop behind the shoulders 14. When the water is cut'otl and the, blades 7 and 9 are relieved of pressure the heads can be disengaged from the said'shoulders and the coupling readily turned to enable the heads 8a to be withdrawn-from the guideways.

What I claim is:

lkThe combination with coacting coupling members, of blades arranged 1n sets in said coupling members, the blades of each set being oppositely disposed, and one set being oppositely arranged with respect to the other.

2. The combination with coupling members adapted to interlock, of oppositely disposed blades carried by said members, said blades being acted on by Water pressure for the purpose of Carrying said heads along said guideways and holding them behind l said shoulders, the lugs being contained en tirely with the coupling member to which they are connected.
